The “W” sit is a position that is normally used as a transition in children during activities of play. Transitioning in and out of this position is ok, but the issue comes when children get “fixed” or stay in that position during seated activities on the floor. The W-sit position allows the child to have their trunk and hips “fixed” so that playing only happens in the front of their body, therefore avoiding trunk rotation and weight shifting. Trunk rotation and weight shifting are important for appropriate bone and muscular development, core strength, balance control, and crossing midline that all help ensure that both sides of the brain are communicating effectively for proper development. Positions like crisscross ankle sit, ring sit, side sit or laying on their stomach or side are all better positions for play! -Physical Therapy Department, Celebrate the Children
